The Lowdown
Alright folks, Rusty here. Let’s be straight with you – the next couple of weeks at Kennebunk Beach are looking pretty grim. I’ve scanned the entire 16-day window and there’s just nothing to get excited about. The wave energy is weak, the swell is tiny, and the wind is mostly making a mess of things. It’s one of those stretches where the forecast is a total dud, so don’t go paddling out with high hopes.
The water temp is sitting at 65°, which is bang on average for this time of year, so at least you won’t freeze while you’re sitting there waiting for a wave that never comes. The first few days are a write-off. Tuesday the 4th through to the end of the first week, we’ve got swell heights barely scraping 3 ft, with periods under 8 seconds – that’s short-period wind slop, not proper groundswell. The combined energy is weak, ranging from 8 to 71 (71), so there’s no punch in any of it. The wind is mostly cross-onshore or onshore, keeping the surface choppy and messy. Even a glassy moment on Sunday morning the 9th with a tiny 1 ft swell is just not enough to ride.
Moving into the second week, it doesn’t get any better. From Monday the 11th right through to Wednesday the 20th, we’re stuck with the same story: small waves, poor surf conditions, and inconsistent energy. There’s a brief moment on Wednesday morning the 12th with a 0.3 ft swell from the southeast but a 14-second period shows some long-period energy – but it’s so tiny it’s barely a ripple. The combined energy at that point is only 11 (11). On Thursday the 13th afternoon, we get glassy conditions with a 1 ft, 8-second SSE swell, but again, it’s just too small to be worth a paddle.
The largest swell of the entire period shows up on the 19th, Wednesday morning, with a 4 ft SSE swell and a combined energy of 96 (96). That’s the most energy we’ll see, but at 6 seconds period, it’s short-period junk, and the wind is cross-onshore, making it choppy. It’s still not good surf. The next day, the energy drops back to just 2 (2).
Honestly, the whole 16-day forecast is a blank run. There are no standout days, no windows of clean surf, no proper swell direction. The break is sheltered and exposed to the ENE, but we’re not getting any of that. For a spot like Kennebunk Beach, this kind of flat, poor run is more normal than you’d hope. If you’re desperate for a water session, the setup looks more interesting for kite surfing than paddle surfing on those days with stronger onshore winds. But for now, leave the board at home and keep an eye on the long-range forecasts.
Rusty.

Information about the Kennebunk Beach Surf forecast
The above surf forecast table for Kennebunk Beach provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Kennebunk Beach can be found by selecting the local surf guide option on the grey menu. Our Kennebunk Beach surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Kennebunk Beach) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Kennebunk Beach may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
